You got to be a bit creative for this one,
You need some M4 30mm bolts
Switch ( i used a 20mm build-in 2 way switch )
Makita connector , ebay .. a old machine or dyi
Truck work light 12-36V ( M8 mount ) its the stock size
And some hot glue , it is all press fit but as i use it in my garage .. stuff drops
down and needs some protection.
The battery mount itself i ninja-stole of source unknown , i am NOT the designer ,
i only made a adapter plate to cobble it together so you have a working light.
I use PETG for strength and chemical resistance
